This function can be used to check if a given address or network has one
of the following network flags.

* LOC_NETWORK_FLAG_ANONYMOUS_PROXY
* LOC_NETWORK_FLAG_SATELLITE_PROVIDER
* LOC_NETWORK_FLAG_ANYCAST

It will return true if the given flag is set.

Hello,

Thank you for sending those.

How are we going to proceed from here? Would you like to build the stuff that is needed for the web UI and if it all works I will tag a release? I would prefer to leave this open for as long we might have to add some more patches.

Best,
-Michael
